KVM: nSVM: Don't assume all active-low bits DR6 are fixed-1
When preparing vmcb02 for nested VMRUN, force only the actual fixed-1 bits
instead of setting all active-low bits. The flaw is currently benign, as
the only active-low bits supported by KVM are RTM (Restricted Transactional
Memory) and BLD (Bus Lock Detect), neither of which is currently supported
on SVM, but that's about to change.
